The only ratings news CNN  is getting lately is bad news. Last week, the cable news network had its lowest-rated weekday primetime in 20 years in terms of total viewers. From May 14-18, CNN averaged 395,000 viewers in primetime with Anderson Cooper’s AC360 and Piers Morgan Tonight. The full seven days of last week was the third-lowest-rated full week in primetime since March 1997.
This ratings news comes less than a week after the network hit its lowest primetime among adults 25-54 in 15 years  on May 15 with Piers Morgan Tonight. That followed a terrible April  where CNN had its lowest-rated month in a decade.
